摘要:
随着新一代组件计算程序计算精度要求的不断提高,组件计算程序对配套多群常数库提出了更高的要求,例如:要求能群结构更加精细、共振参数更加多样、燃耗数据更加精确等.为满足新一代组件计算程序的这一系列需求研发了一套制作多群常数库的系统NPLC-3.NPLC-3系统以NJOY程序为中心包含了输入参数库、驱动程序、主库制作程序、并群、并库、删除、添加、进制转换、数据自动检验等功能模块,针对各功能模块采用不同方法初步验证了系统的正确性.相对传统的数据制作方法,NPLC-3系统在燃耗链设计、燃耗数据计算以及共振数据制作等方面增加新的特性,而且系统采用独立的I/O接口、全自动读取参数库并生成输入卡,相对过去制作数据库的手段有了很大的改进.
Abstract:
With the unceasing enhancement of the calculation accuracy requirement on the new generation of lattice code,higher requirements on multi-group constants library were put forward.For example,fine energy group structures are required,more types of data are need for the resonance processing,more accuracy burn-up data is required.To meet this series of demand,a multi-group constants production system NPLC-3 was developed.The NPLC-3 system which mainly based on the N JOY program contains an input parameter database and a series of functional codes such as driver code,main library production code,energy group collapsing code,work library production code and so on.Recently,different methods were adopted to validate these codes respectively according to their functions.Compared to the traditional methods in multi-group constants production,NPLC-3 system adopts several new methods in the design of burn up chain,calculation of burn up data and resonance parameters.What's more,the NPLC-3 system has an independent I/O interface,and can fully automatic generate input cards from the input parameters database.Relative to the past means of production library,NPLC-3 system has great improvement.
